Please note that a bent wheel can be balances spinning in the air but will ride rough. A tire with a slipped belt can ride rough. A careful visual inspection during balancing should find such things. You can jack up each tire to the point where it just scuffs the pavement when turned, finding that high spot(s), then rotate to find the widest gap to pavement. A bent wheel will typically be mostly deformed on the inboard rim.
Failing universal joints can also create shaking.
Many tires are not round. But when new and supple, they run fine. Add a few summers of age hardening and they can become unbearable. State of the shocks can affect the result. Performance tires, or run-flats, have stiff sidewalls are are more prone to these age hardening defects.
